The Mechanics of a Cream Separator Cleaned and Sterilized by Centrifugal Force

Abstract
The trend in the dairy industry is toward automation. The authors have explained the mechanics of a cream separator which is cleaned and sterilized by centrifugal force. This is made possible by a rubber-covered steel ring in the bowl. It can contract or expand depending on the velocity. At normal bowl velocity, the ring fits tightly against openings in the shoulder of the bowl shell, but when the velocity decreases, the ring relaxes and sanitizing solutions flow turbulently through these openings. It was calculated that the bowl released these solutions into the cream and skim milk assembly at a pressure of 109 psig.
